Title: Machine applying ribs of iron on adhesive interfacing - has two adhesive tanks dispensing composite ridges
Inventor: HEFELE JOSEF DR
IPC: C09J7/21
Filed: 1975-08-19
Abstract: The interfacing for ironing on to the prepared material has a higher melting point layer underneath to save the adhesive upper layer from soaking downwards into the cloth and losing its effect.

Title: Timer with dropout delay for reactor protection - has two input stages and pulse converter for output transistor base
Inventor: CENTMAIER WALTER
IPC: H03K19/21
Filed: 1975-12-10
Abstract: A timer with a drop-out delay for pulsed logic system as used for the protection of reactors receives a first pulse signal input in an input stage for a pulse d.c. converter.
